IMPROVED EXTENSION-TABLE.

Sp ecication forming part of Letters Patent No. 91,099, dated June 8,1869.

To all whom, t may concern:

. Be it known that I, JACOB DOURSON, of Columbus, in the county ofFranklin and State of Ohio, have invented a new and useful Improvementin Fall-Leaf Extension-Tables; and I do hereby declare the following to-be a full, clear, and exact description of the same, suicient to enableothers skilled in the art to which my invention appertains to make anduse the same, reference being had to the accompanying drawings, formingpart of this specication, in which Figure 1 is a longitudinal centralsection of Fig. 2. Fig. 2 is aninverted plan view of my table when notextended. Fig. 3 is a detail View, to be hereinafter referred to.

The present invention is an improvement on the extension-table patentedto me March 16, 1869.

-The object is to. so arrange or combine the slides that the frame ofthe table can be drawn out to such an extent as to render the auto- 1matic supports unnecessary. The latter may of the slides,as hereinafterdescribed, so as to permit the increased extension of the frame -k andadapt my improvement to extension-tables of large dimensions.

My invention will be fully understood by reference to the accompanyingdrawings, considered in connection with the following detaildescription.

Similar letters of reference indicate like parts in the several gures.

In the drawings, A represents the top of the table, and B B the leaves.

C C C C are the legs, of which the two on each side of the table areconnected together by strips D, D. Y

E E are blocks secured immovably to the under side of the top A, andhaving longitudinal grooves in both sides to receive the projections ofthe metallic slides 2T, attached to the end pieces F F of thetable-frame. The slides t' being fully described in my former patent,above referred to, a further speciiication of'them is deemed unnecessaryhere. y I

In my former patent the pieces F F, which are secured to the legs C C,are arranged on the outer sides of the fixed blocks E E. In the presentcase, as will be seen by referring to Fig. 2, the two pieces F at thesame end of' strengthened, as before stated, by similar slides i,attached to the inner ends of the pieces F and tting in grooves in thestationary part E.

If it be desired to employ auxiliary supports for the leaves, eithertwo, as in my former`patent, or one, as in this case, can be used. foreach leaf. In the present case, G G

represent the auxiliary supports, which vare simply Wooden stripscentrally pivoted to the upper sides of the parts D, and having longif`tudinal grooves in the upper side, which receive pins a, fixed in thetop A of the table underneath. When the sides D of the frame are drawnout, the auxiliary supports are brought automatically to the positionshown in red lines, Fig. 2. y

My improvement may be adapted to extension-tables of large dimensions byincreasing the number of slides F F, as shown in redv lines, Fig. 3, andattaching the outer slides of t-he series to the legs of the table.

I-Iaving thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is;-

The arrangement of the slides F F, which are connected with thetable-legs on oppositel sides of the blocks E, when the latter areattached to the tabletop A, and are connected with the parts F F bymeans of the metallic slides il t, all constructed and arranged tooperate substantially as described, and for the purpose speciiied.

To the above I have signed my name this 27th day of March, 1869. l
